The use of sensors has become increasingly accepted as an innovative solution for a diverse range of functions and needs. The University of North Florida's Nanocrystalline Enhanced Quartz Microbalance Sensors, also known as NCQCM sensors, can be trained to "electronically sniff" and detect in near real-time almost any combination of mixtures. UNF NCQCM Sensors are cutting-edge technology and their applications are numerous. Potentially, government agencies can have a more advanced way to ensure national security, the medical field can rapidly diagnose illnesses, and the quality and consistency of manufacturing and agriculture goods can be carefully monitored and maintained.
Nanocrystalline enhanced quartz crystal microbalance sensing is accomplished through the absorption and desorption kinetics of gases, vapors, and odors modifying the dampening of the crystal's resonance vibration frequency. UNF NCQCM sensors are electronic "e-noses," or devices that can learn to recognize mixtures or combination of mixtures. In other words, they are capable of mimicking the human senses of smell and taste. This innovative technology can categorize and identify mixtures, and then determine the brand, and then, if the brand fits within established standards of quality. For example, UNF NCQCM sensors can determine if an unknown liquid is rum, and if that rum is Bacardi, and if so, if the sample satisfies the quality standards for Bacardi.
NCQCM sensors are patent-pending and, when used orthogonally with the UNF NOS sensors, provide an even higher level of superior selectivity and sensitivity. In identifying what is in the mixture being sensed, UNF NCQCM sensors are customizable and can be configured to detect a wide range of analytes. At present, they have been tested with over 160 mixtures including alcoholic beverages (individual types and brands), teas (brands), marker pens (brands), vapors, food and fruit products, explosive materials, petroleum fuels, adulterated fuels, alkenes, volatile organic compounds, aldehydes, ketones, and esters. See the detailed list of analytes. The sensors work at room temperature and the response time of the sensors is in near-real time. Additionally, the size of the quartz crystal holder and frequency measurement circuits can be miniaturized allowing for more design alternatives. UNF NCQCM sensors have increased sensitivity that is determined using Principal Component Analysis.
UNF NCQCM sensor applications are varied and numerous. In addition to the potential uses listed below, contact us to learn how UNF sensor technology can be tailored to meet your particular needs.
